gumstix boot console output.txt
|
I have an Ubuntu Maverick install that I built for a Gumstix which is not booting properly. It booted once, and for every boot after that, it has thrown the following error (entire console output attached): Waiting for root device /dev/mmcblk0p2... mmc0: host does not support reading read-only switch. assuming write-enable. mmc0: new high speed SDHC card at address b368 mmcblk0: mmc0:b368 00000 7.51 GiB mmcblk0: p1 p2 EXT3-fs: barriers not enabled mmcblk0: error -110 sending read/write command, response 0x900, card status 0xe0 mmcblk0: error -110 transferring data, sector 13093213, nr 8, card status 0xc00 end_request: I/O error, dev mmcblk0, sector 13093216 Buffer I/O error on device mmcblk0p2, logical block 1626611 lost page write due to I/O error on mmcblk0p2 JBD: recovery failed EXT3-fs (mmcblk0p2): error loading journal List of all partitions: b300 7875584 mmcblk0 driver: mmcblk b301 40131 mmcblk0p1 b302 7823655 mmcblk0p2 No filesystem could mount root, tried: ext3 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2) Any ideas why? Does anyone have a fix? Thanks, Bradley Powers |

My first two tests would be, 1) try a different mmc card, 2) try an angstrom image. This would help distinguish between a hardware problem or a kernel problem and isolate whether just the maverick kernel is affected. -Ash |
